So far so good, my second one, the first when arrived (not ordered from Wayfair) did not work and the manufacturer said the board was probably fried and replacement boards were on back order and not available.  No assistance provided by manufacturer other than that I personally bring it back to the place of purchase.   Only bought the second unit because Wayfair had a good price,  I am keeping my fingers crossed.   Probably would not recommend the unit, I did buy an extended warranty.    If it operates OK for the next year or so I may change my mind.
